Features of ultra-thin FFU fan filter unit and low resistance fan filter unit
Features of ultra-thin FFU fan filter unit and low resistance fan filter unitFFU fan filter unit can be connected and used in a modularized way. FFU is widely used in clean rooms, clean workbenches, clean production lines, assembled clean rooms, and local 100-level applications.FFU is equipped with primary and high-efficiency filters. The fan sucks air from the top of the FFU and filters it through primary and high-efficiency filters. The filtered clean air is uniformly delivered at a wind speed of 0.45M/S±20% on the entire air outlet surface. It is suitable for obtaining a high-quality clean environment in various environments. It provides high-quality clean air for clean rooms and microenvironments of different sizes and cleanliness levels. The renovation of new clean rooms and clean workshops, can improve the cleanliness level, reduce noise and vibration, and greatly reduce the cost. It is easy to install and maintain and is an ideal component for clean environments. FFU features: 1. The fan adopts the German ebm direct-drive high-efficiency centrifugal fan, which has the characteristics of long life, low noise, maintenance-free, low vibration, stepless speed regulation, etc. The fan is of reliable quality and has a working life of 5 hours or more. 2. It is particularly suitable for assembly into an ultra-clean production line. It can be arranged as a single unit according to the process requirements, or multiple units can be connected in series to form a 100-level assembly line. 3. The shell structure is made of stainless steel, aluminum alloy, and cold-rolled steel plate materials, which are light in weight, corrosion-resistant, rust-proof, and beautiful. 4. Before leaving the factory, the products are scanned and tested one by one according to the US Federal Standard 209E and the METOME dust particle counter to ensure quality. Its advantages are as follows: 1. The system is very flexible and can be adjusted at any time. Because the wall panels of the clean room are arranged according to the modulus of the ceiling grid (such as 1200*600), and due to its special node structure, the wall panels of the clean room can be adjusted at any time to change the layout of the room. At the same time, if the cleanliness of the room needs to be adjusted, it can be achieved by increasing or decreasing the number of FFUs. This is almost impossible for the purification system with a centralized air supply. 2. Uniform and stable air output FFU has a fan, so the air output is uniform and stable. The problem of air volume balance at each air outlet of the centralized air supply system is avoided. It is particularly beneficial for vertical unidirectional clean rooms. 3. Energy saving FFU system has very few air ducts. In addition to the fresh air delivered by the air duct, a large amount of return air is running in a small cycle, which greatly reduces the resistance consumption of the air duct. At the same time, since the surface wind speed of FFU is generally 0.35~0.45m/s, the filter resistance is small, and the power of FFU's shellless fan is very small. The new FFU uses a high-efficiency motor, and the shape of the fan impeller has also been improved, and its comprehensive efficiency has been greatly improved. According to the author's estimate, the FFU system can generally save more than 30% of energy compared with the centralized air supply purification system, so the FFU system can save the increased initial investment (compared with the centralized air supply purification system) by saving electricity bills within two or three years. 4. Space saving Since the huge return air duct is omitted, the installation space can be saved. It is very suitable for renovation projects with tight floor heights. Another benefit is that the construction period is shortened because there are few air ducts and the space is relatively spacious. 5. Reasonable layout of air vents, lamps, smoke detectors, sprinklers, static neutralizers, etc. These commonly used devices in clean rooms all have their installation ceiling grid positions, which are both reasonable and beautiful. In the centralized air supply purification system, the layout of these devices often conflicts, and the ceiling appears crowded. |
